Blockchain wallets

Full addresses · public payment evidence

Receiving wallets are payment addresses published for this service. Sending wallets transferred funds to an exclusive receiving address; this alone does not prove a purchase or identify an agent.

Coverage includes retained scans only, not every historical transaction. Earlier daily totals cannot recover sender addresses. Sender lists exclude shared receiving wallets, whose transfers could belong to another service. A provider address does not establish wallet ownership.

Where you can pay

2 routes from the provider's payment requirements
Payment networks and amounts published for BTC USD.
Network Scheme Amount Asset

Opportunity insights

2 findings from measured data
  • Two independent sources agree

    The observed inflow implies about 47 calls at list price; the source counted 71 (factor 1). A transfer is still not a purchase, but the order of magnitude holds — this is the strongest monetisation signal in the catalogue short of a receipt feed.

Money, and what it actually proves

Verified revenue · 30d Unknown
Observed inflows · 30d $0.094
Attribution Exclusive
Receipt ledger Not connected

Observed transfers · confidence medium
Token transfers reached this service's own payout address. A transfer is not a purchase, and shared, refunded or unrelated transfers cannot be excluded.

Why revenue is “unknown”. A revenue figure needs a receipt: an amount a buyer actually paid for this service. We hold none for this entry, and we hold no funds at all. What we have instead is $0.094 arriving at the payout address in 30 days — that is volume, and a lower bound: transfers can be refunds, treasury moves, or payments for something else entirely.

Cross-check. At the published price the observed inflow would cover about 47 calls; the source counted 71. Two independent measurements of the same question — they never match exactly, because the effective price differs per call size and the address can also receive unrelated transfers.
